I guess, you have tried adding the "Service Referemce". Instead call the php directly from webclient.
public Sample()
{
InitializeComponent();
WebClient wc = new WebClient();
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(doProcess);
wc.DownloadStringAsync(new Uri("http://mydomain.com/webservices/getLogin.php") );
return;
}
void doProcess(object sender, DownloadStringCompletedEventArgs e)
{
string res = (String)e.Result;
}
This should work.
cheers
